What are All formulas used in surface area and volumes

1.	What are All formulas used in surface area and volumes
Answer» Volume of cuboid=lbh . Total surface area of cuboid =2 (lb+bh+hl). Curved surface area of cuboid =2h (l+b). Volume of cube=a×a×a . T.S.A. Of cube 6a×a . C.S.A. of cube =4×a×a. T.S.A. Of cylinder=2×py×r(h+r). C.S.A. of cylinder =2×py×r×h. Volume of cylinder =py×r×r×h . T.S.A. OF cone=py×r (l+r) . C.S.A. of cone =py×r×l . VOLUME of cone =1/3×py×r×r×h. T.S.A of sphere =4×py×r×r . C.S.A. of sphere =4×py×r×r. Volume of sphere =4/3×py×r×r×r.C.S.A of hemisphere =2×py×r×r. T.S.A of hemisphere =3×py×r×r.volume of hemisphere =2/3×py×r×r×rC.S.A of frustum =py×l (r1+r2) +py (r×r1+r×r2). T.S.A of frustum =py×l (r1+r2) + py (r×r1+r×r2). Volume of frustum =1/3×py×h (r×r1+r×r2+r1×r2)
